The heat collecting tube 15 is disposed horizontally inside the top of the roof 2 and has a suction port 16 at a position corresponding to the exhaust port 11 of the heat collecting panel 12 in the longitudinal direction. Exhaust port 11
And the suction port 16 may be separated as shown,
You can also connect directly.

The falling blower tube 17 connects an opening at the upper end to the lower center of the heat collecting tube 15, and opens another suction port 30 below the middle height position of the falling blower tube 17, An electric blower fan 20 is attached below the suction port 30.

The heat storage tube 18 is connected to one main pipe 18a at the center in a direction perpendicular to the ridge 21 in the greenhouse 1, and is parallel to the ridge 21 so as to be located between the ridges 21 from both sides of the main pipe 18a. Multiple branch pipes
18b was connected. The end of the branch pipe 18b has a length reaching the side of the greenhouse 1.

The heat storage tubes 18 are provided with a plurality of containers, such as plastic bottles filled with water, as heat storage bodies 22 connected in the longitudinal direction inside each branch pipe 18b. in this case,
As shown in FIGS. 9 and 10, the heat storage body 22 is connected to the branch pipe 18b via a packing 23 serving as a support member at a plurality of locations in the circumferential direction.

If the temperature inside the greenhouse 1 cannot be maintained at a predetermined value only by blocking the air with vinyl in a cold region or the like, the heat collection panel 12 can be installed inside the roof 2 of the greenhouse 1 as a means for temperature correction. The sunlight is irradiated on the heat collecting plate 7 through the light transmitting plate 5 of the panel 12 to be heated.

The air in the greenhouse 1 is supplied to the air inlet 10 of the heat collecting panel 12.
The air heated by the heat from the heat collecting plate 7 rises along the heat collecting plate 7 and enters the space between the light transmitting plates 5 and 6 as shown in FIG. Flows through an air flow passage 8 formed between the upper surface of the heat collecting plate 7 and the light transmitting plate 5 to reach the exhaust port 11.

The air that has not flowed toward the upper surface of the heat collecting plate 7 passes through an air flow passage 9 formed between the lower part of the heat collecting plate 7 and the light transmitting plate 6 on the lower side, and is heated during this time. To exhaust port 11.

The warm air thus heated in the heat collecting panel 12 and discharged from the exhaust port 11 is sucked into the heat collecting tube 15 from the suction port 16 by the suction force of the blower fan 20, and The air further flows through the connected falling air pipe 17 and flows into the heat storage pipe 18 buried underground, where the main pipe 18

The warm air flowing into the rising blower pipe 19 blows warm air into the greenhouse 1 from the outlet 25 at the upper end. Since a plurality of the descending blower tubes 19 are arranged at substantially equal intervals along the side wall of the greenhouse 1, warm air is blown out uniformly to each part in the greenhouse 1. The sunlight passing through the light transmitting plate 6 through the gap 13 between the heat collecting plates 7 of the heat collecting panel 12 irradiates plants and the like in the greenhouse 1 as direct sunlight and heats the greenhouse 1.

Even at night or when there is no sunshine, the heat stored in the water of the heat storage body 22 provided in the heat storage tube 18 is radiated to the surrounding soil, thereby preventing the temperature of the greenhouse 1 from dropping. In this case, the branch pipe
Since the portions 18b are arranged along the ridges 21, each portion in the greenhouse 1 can be heated almost uniformly. The heat storage element in the heat storage tube 18
The heat from 22 into the soil warms the soil around the pipes, preventing the soil from freezing in cold regions, especially in winter.

Further, at night or when there is no sunshine, the side wall of the lower part of the greenhouse is covered with the heat insulating panel 27 and the greenhouse 1
A heat insulating panel 28 is arranged at an intermediate position of the inside space to divide the inside of the greenhouse 1 into upper and lower parts, forming a narrow space closed only in the lower part where plants are growing, and sucked from the suction port 30. The circulating hot air blown from the outlet 25 efficiently heats only this narrow space.

In winter, by covering the entire north side of the greenhouse 1 with the heat insulating panel 26, heat radiation on the north side without sunshine can be prevented. Installation of such insulation panels 26-28 need only be leaned or placed.

FIGS. 11 and 12 show a second embodiment of the greenhouse.
The heat collecting device 4 was separately provided outside the greenhouse 1. As the heat collecting device 4 in this case, for example, the heat collecting panel 12 described in Japanese Patent Application Laid-Open No. 9-26211 filed by the applicant can be used. This may be made of a heat insulating material instead of the light plate 6.

The heat collecting device 4 is a heat collecting panel 12 in the illustrated example.

It is horizontally arranged on the uppermost part under the roof 2 inside, and a suction port 34 is provided on the upper surface and the end.

Then, when there is sunshine, the air warmed by the heat collecting panel 12 falls from the heat collecting tube 15 and is sent to the blower tube 17, and is discharged through the heat storage tube 18 and the rising blower tube 19.
It blows out into the greenhouse 1 from 25, and the temperature in the greenhouse 1 is maintained at a predetermined value or more.

The air in the greenhouse 1 is sucked in from the suction port 34 of the suction pipe 33, and is blown out again into the greenhouse 1 from the blowout port 25 together with the warm air from the heat collecting pipe 15. As a result, a suitable amount of fresh outside air is taken in from the side of the heat collecting panel 12, and ventilation can be performed.

At night, as in the first embodiment, the lower half of the side wall of the greenhouse 1 is covered with the heat insulating panel 27 to reduce the space that needs to be kept warm, and the air blown out from the outlet 25 is supplied to the inlet 30 in the middle. Inhale only from

Accordingly, the space in which the hot air circulates is greenhouse 1
It is only the lower half inside, and at night or on days without sunshine, heat storage tubes 18
